Can I replace a toilet fill valve myself without professional help?
Yes, many homeowners can replace a toilet fill valve themselves. However, we recommend a pro when symptoms include constant running, poor flushing, leaks, clogs, or unusual noises. A licensed plumber will also check the fill valve, flapper, handle, rim weep holes, and gaskets so the fix lasts. We offer 24/7 emergency service if the toilet won’t stop running.
Quick steps:
- Shut off water and drain the tank.
- Swap the fill valve.
- Set water level and test for leaks.
